Abstract

The structural-functional organization and dynamics of the aquatic-terrestrial ecotone system of the Ded-Khulsun Reservoir for 2012—2015 are investigated in the paper. Regularities of the composition and structure of the reservoir ecotone system are identified. It is determined that the structural and functional organization of the ecotone system “water-land” has common features and patterns that are typical for the majority of reservoirs in the arid areas: the impact of the reservoir is more pronounced on amphibian, fluctuation and dynamic blocks. The features of the flora composition in every block are characterized in accordance with the field studies results. It is shown, that like the majority of basins in Kalmykia, water economic value of the Ded-Khulsun Reservoir decreased at present in comparison with the moment of its creation. However, it increased the environment-forming role of the Reservoir now.

Keywords
